Specification of Letters Patent.

Patented Dec. 19, 1905.

Application filed May 3, 1905. Serial No. 258,634-

To col] whom, it may concern:

Be it known that I, LEONARD D. SHRYOOK, a citizen of the United States, residing at Marietta, in the county of Washington and State of Ohio, have invented certain new and useful Improvements in ell-Drilling Apparatus, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to machines for drilling oil, gas, and other deep wells, and has particular reference to the general type of portable machines shown in my Letters Patent No. 781,234, January 31, 1905, and No. 783,227, February 21, 1905.

The objects of the invention are to improve the construction of the machine-frame, the Samson-post, the walking-beam, and the mast.

A further purpose is to provide the machine with an additional reel for receiving a line for raising and lowering well-casing, together with improved means for actuating the reel.

Still further objects are to improve the construction of the drilling-cable reel; to detachably mount the band-wheel on its shaft in such manner that the wheel may be readily removed from and without disturbing its secured hub, and to provide clutch-throwing mechanism of novel form.

lVith these and other objects in view, as will presently appear, the invention consists in the novel features of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, wherein 5 Figure 1 is a side elevation of a drillingmachine embodying the several improvements with part of the walking-beam broken away and illustrating only a portion of the mast. Fig. 2 is a top plan view. Fig. 3 is a vertical longitudinal sectional view. Fig. 4 is an edge view of the samson-post, together with that portion of the machine-frame upon which it is mounted; and Fig. 5 is a sectional plan view of the same. Figs. 6, 7, and 8 are detail views of portions of the mast, Fig. 8 being a cross-section taken on line 8 8 of Fig. 7. Fig. 9 is atop plan view of the machineframe; and Figs. 10 and 11 are cross-sections thereof, taken on lines 10 10 and 11 11, respectively, of Fig. 9. Figs. 12 and 13 are detail views illustrating the construction of the band-wheel. Fig. 14 is a cross-sectional view of the walking-beam.

Referring to the drawings, the machineframe consists of the outerlongitudinal side beams 2 and 3, connected near their rear ends by cross-bar 4 and at the front by two crossbars 5 and 5', while secured between the last two mentioned bars are longitudinal bars 6 and 6. All of the beams and bars thus forming the frame are preferably of standard channel-section, as in practice I have found that steel of this section produces a frame of maximum strength and one which is far lighter than a frame of the necessarily heavy wood construction shown in'my patents above re ferred to.

The bearings for the several shafts are mounted on the upper edges of the frame sides, and in order to provide supports of sufficient width therefor the channel side beams are made double for portions of their length, the channel members in such construction being secured back to back, as shown. Thus for the band-Wheel side of the frame an additional channel member 7 is secured to beam 2 and may conveniently extend from bar 4 to bar 5, as shown. For the opposite side of the frame a short channel member 8 is extended forward from bar 4 and secured to beam 3, and also secured to the inner side of the latter at a point forward from member 8 is the short channelsection 9.

10 designates the shaft which supports sand-line reel 11, while forwardly therefrom is the main band-wheel shaft 12, and still farther forward is shaft 13, upon which is wound the drilling-cable A.

Bearings 14 and 15 at each side of the machine for shafts 10 and 12, respectively, are preferably mounted in short channel -'supports 16, which bear flatly on the sides of the machine-frame with their flanges and channels uppermost, support 16 at one side of the frame resting on frame members 2 and 7 and for the opposite side resting on members 3 and 8. As it is necessary to provide for adjusting shafts 10 and 12 either forward or backward, a screw adjustment 17 is provided at the rear end of each support 16. Bolts 14, which secure bearings 14, extend through the top flanges of the supporting-frame members, and as bearings 14 have fixed position in channel-supports 16 the flanges of the frame members are slotted, as indicated at 14", to provide for the above-described adjustment. Securing-bolts 15 for each of bearings 15 of band-wheel shaft 12 are preferably extended through both the upper and lower flanges of the frame members, as shown, and have fixed tion 31 of the band-wheel.

position in order to securely and positively hold said bearings, and hence provision is made for the above-described adjustment by slotting bearings 15, as indicated at Bearings 18 for reel-shaft 13 are secured directlyto the frame sides, the bearing on one side being secured to frame members 2 and 7 and on the opposite side to frame member 3 and short channel member 9.

At one end of shaft 13. is the usual bandbrake wheel 19, which forms one of the reelheads for confining the drilling-cable A on shaft 13, as will be understood, the other head being formed by disk 20. The inner face of wheel 19 is preferably flat, and the rim thereof is projected outward sufliciently to obtain the necessary band-braking surface, said rim projecting into the planes of frame members 8 and 9. Hence by providing the short bearing-supporting channel members 9, Y.ill0l1 project into wheel 19, rather than extending member 8 forward to form that sup port, wheel 19 may be placed farther outward on shaft 13, and thereby appreciably increase the length of the cable-space on the reel. Band-brake 21 is operated in the usual manner by lever 21.

Bolted to the outer face of disk is sprocket-wheel 22, which is driven by chain 23, extending from sprocket-pinion 24, loose on shaft 12. Also loose on said shaft is a spool 25, upon which is wound a casing elevatorline, which is used for the purpose presently to be described. Slidable on shaft 12, between pinion 24 and spool 25, is the double clutch 26, one end of which is adapted to interlock with the sprocket-pinion and the other end with said spool. As pinion 24 is rotated only for the purpose of winding up the drilling-cable A and as this operation is never performed while the cable B, extending from spool 25, is in use, one or the other of said parts is always at rest, or the clutch may be placed in neutral position, when neither of said parts will be rotated. Arranged transversely in the frame are two rods 27 and 28, and projecting from the former is arm 27, uponwhich is fulcrumed the clutch-throwing lever 29. Depending from rod 23 is hanger 28, and fulcrumed thereon is the long operating-lever 30, which extends to the front of the machine and which at its rear end is connected to lever 29, whereby the clutch may be conveniently thrown by an operator positioned at the front of the machine.

The improved mounting for band-Wheel 31 on main shaft 12 is illustrated in Figs. 12 and 13. Secured to the end of said shaft is a hub 32, formed between its ends with the annular plate-like flange 33, and removably fitting over the outer portion of the hub and bearing against this flange is the web or center por- With the latter thus in place a washer-like plate 34 is moved inward over the outer end of the hub, and

bolts 35 are passed through flange 33, wheelweb 31, and plate 34, thereby firmly clamping and securing all of said parts together. When the wheel is to be removed, it is only necessary to release bolts 35, when plate 34 and the wheel may be readily slipped from the hub without disturbing the fixed position of the latter on shaft 12. In machines of prior construction it has been necessary to unkey the wheel, the wheel proper and the hub being inseparable. With the construction herein proposed the wheel may be quickly and conveniently removed either for the purpose of transportation or repairs and may be as conveniently replaced. As the hub remains undisturbed upon the shaft, the tedious operation of centering the wheel each time it is replaced is avoided.

The samson-post is positioned adjacent the front of themachine, as shown, and is preferably formed of two channel-bars 36, which are separated by the timber 37, the whole being secured together by bolts. The lower end of the post extends downward along the inner side of frame-channel 3, to which itis bolted, and the outer side of the post is cut inward, so that it may overhang and rest on said channel member, as shown. When not in use, the post may be lowered or turned backward, as indicated in dotted lines in Fig. 1, as when being shipped or moved from place to place, and to provide for this backward turning movement the post is hinged at 38 on rod 38, and when the post is unbolted from frame member 3 it may be slid inward on said rod, as indicated in dotted lines in Fig. 2, and thereby brought to position for turning over wheel 19. As the post stands at an angle to the machine-frame, it is necessary to thus move it inward. Otherwise it would be projected laterally and in the way when turned down.

When in upright or operative position, the Samson-post leans backward in order that the heft of the work transmitted thereto from the walking-beam may be thrown on the machineframe backward from its forward end, and thus cause the machine to stand more steadily and prevent it from tilting or cantingan objection incident to those machines wherein the Samson-post rises vertically from the front of the frame. Removable braces 39 and 39 secure the post in its inclined position, brace 39 extending backward and downward to the frame and cooperating with the backwardlyleaning post in throwing the weight of the beam rearward from the front end of the frame.

The timber center 37 of the samson-post stops short of the upper ends of channels 36, thereby providing a space in which the walking-beam is suspended. The journal 40 of the latter is purposely arranged at the upper side of the beam rather than its lower side, as is now the general practice, for with such arrangement the machine is found to operate more steadily and with less rocking motion than heretofore. The beam is of steel construction and consists of a flat body or web part 41, to the upper and lower edges of which are riveted the opposing angle-bars 42. Depending from the beam is the usual pitman 43, which connects with crank 12 of shaft 12.

Then the machine is in operative position, a single-column mast rises from in front thereof for supporting at its upper end crown-pulley 44, over which the drilling-cableA works in usual manner. In construction the mast is much like the Samson-post, consisting of the opposite channels 45, which are separated by a timber center 46, the latter stopping short of the upper ends of channels 45 to provide a space for the crown-pulley. A mast of this construction is very strong and serves every purpose of the two-column mast heretofore used in this type of machines. Journaled on opposite sides of the mast a short distance below the crown-pulley are sheaves 47 and 48, the former being provided for sand-line C, which is employed in the usual manner for operating the bailer. Sheave 48 operates in conjunction with an additional cable B,'which passes thereover from spool 25, this additional cable forming a distinctive feature of the present invention. The primary purpose of said cable is for raising and lowering casing. The sand-line and its reeling mechanism'are not sufficiently strong for this work, and heretofore it has been the practice to raise and lowerthecasingwiththedrilling-cableA. At such time the greater portion of the drillingcable is reeled upon its spool, and with a coil of considerable diameter it has been found difficult to impart sufficient power through the reel and large coil of cable, especially when the cable is subjected to great stress, as it frequently is when lowering and withdrawing casing from a well. With the additional cable and spooling, mechanism therefor herein proposed the cable may be much shorter, and hence forms a much smaller coil than the drilling-cable. Furthermore, this spool is mounted directly on the main shaft, and the power is directly applied for reeling the cable, as

when withdrawing casing.

The improved machine is equipped for spudding as well as beam-drilling, being provided at its rear end with the spudding-line guidewheel 49 and at its front with the spuddingarm 50. These parts are arranged and operate in the manner shown and described in my former patents, to which reference may be made. Variously other features of the machine are also shown in the drawings, which have not been specifically described, the use and purpose of which are obvious to those skilled in the art.
